Title: Decoding system for picture signal
Inventor: NEMOTO KEIJI
IPC: H04N19/186
Filed: 1990-07-13
Abstract: PURPOSE:To reduce block distortion caused in a decoded picture considerably by applying interpolation processing to a block subject to interpolation processing through the use of a decoded mean value and a decoded mean value of surrounding blocks so as to generate a decoded picture of the block. CONSTITUTION:A DCT transformation section 2 applies 2-dimension discrete cosine transformation to a read picture signal 101 by one block to calculate (8X8) sets of transformation coefficients 102 including a DC component as a block mean value. Thus, the calculated transformation coefficients 102 are coded by a coding means 3 to output a code 103. Then a receiver side decoding means 4 receives the code 103 to generate (8X8) sets of transformation decoding coefficients 104 including the DC component as a decoding mean. A discrimination means 5 applies discrimination processing to a block as to whether or not interpolation processing is to be applied based on the transformation decoding coefficients 104 and when it is discriminated that the interpolation processing is to be applied, an interpolation means 7 uses a decoding means value of the block and a decoding mean value of surrounding blocks to apply interpolation processing to generate a decoding picture 107.

Abstract: PURPOSE: To easily recognize the durability of a socket without complicating the configuration of a memory card by sticking a count seal, on which the number of times of insertion/taking out of the socket of a ROM package is previously recorded on the memory card. CONSTITUTION: On the respective surfaces of ROM sockets 4 and 4, count seals 5 and 5 are stuck for recording how many times a ROM package 3 is inserted/ taken out to the socket 4, and description columns for the number of times of insertion/taking out of the ROM socket 4 to a printed circuit board 1 are previously printed on the count seals 5 and 5.
